最近在android 4.0.4系统下实现apk的静默安装和启动的功能,这里和大家分享一下,希望能有所帮助。
源码如下:
- import java.io.DataOutputStream;
- import java.io.File;
- import java.io.IOException;
- import java.io.OutputStream;
- import java.util.ArrayList;
- import java.util.List;
- import android.content.Context;
- import android.content.Intent;
- import android.content.pm.ActivityInfo;
- import android.content.pm.PackageInfo;
- import android.content.pm.PackageManager;
- import android.content.pm.ResolveInfo;
- public class InstallApkUtils {
- public static void installAndStartApk(final Context context, final String apkPath) {
- if ((apkPath==null) || (context==null)) {
- return;
- }
- File file = new File(apkPath);
- if (file.exists() == false) {
- return;
- }
- new Thread() {
- public void run() {
- String packageName = getUninstallApkPackageName(context, apkPath);
- if (silentInstall(apkPath)) {
- List<ResolveInfo> matches = findActivitiesForPackage(context, packageName);
- if ((matches!=null) && (matches.size()>0)) {
- ResolveInfo resolveInfo = matches.get(0);
- ActivityInfo activityInfo = resolveInfo.activityInfo;
- startApk(activityInfo.packageName, activityInfo.name);
- }
- }
- };
- }.start();
- }
- public static String getUninstallApkPackageName(Context context, String apkPath) {
- String packageName = null;
- if (apkPath == null) {
- return packageName;
- }
- PackageManager pm = context.getPackageManager();
- PackageInfo info = pm.getPackageArchiveInfo(apkPath,
- PackageManager.GET_ACTIVITIES);
- if (info == null) {
- return packageName;
- }
- packageName = info.packageName;
- return packageName;
- }
- public static List<ResolveInfo> findActivitiesForPackage(Context context, String packageName) {
- final PackageManager pm = context.getPackageManager();
- final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
- mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
- mainIntent.setPackage(packageName);
- final List<ResolveInfo> apps = pm.queryIntentActivities(mainIntent, 0);
- return apps != null ? apps : new ArrayList<ResolveInfo>();
- }
- public static boolean silentInstall(String apkPath) {
- String cmd1 = "chmod 777 " + apkPath + " \n";
- String cmd2 = "LD_LIBRARY_PATH=/vendor/lib:/system/lib pm install -r " + apkPath + " \n";
- return execWithSID(cmd1, cmd2);
- }
- private static boolean execWithSID(String... args) {
- boolean isSuccess = false;
- Process process = null;
- OutputStream out = null;
- try {
- process = Runtime.getRuntime().exec("su");
- out = process.getOutputStream();
- DataOutputStream dataOutputStream = new DataOutputStream(out);
- for (String tmp : args) {
- dataOutputStream.writeBytes(tmp);
- }
- dataOutputStream.flush(); // 提交命令
- dataOutputStream.close(); // 关闭流操作
- out.close();
- isSuccess = waitForProcess(process);
- } catch (IOException e) {
- e.printStackTrace();
- }
- return isSuccess;
- }
- public static boolean startApk(String packageName, String activityName) {
- boolean isSuccess = false;
- String cmd = "am start -n " + packageName + "/" + activityName + " \n";
- try {
- Process process = Runtime.getRuntime().exec(cmd);
- isSuccess = waitForProcess(process);
- } catch (IOException e) {
- NLog.i(TAG, e.getMessage());
- e.printStackTrace();
- }
- return isSuccess;
- }
- private static boolean waitForProcess(Process p) {
- boolean isSuccess = false;
- int returnCode;
- try {
- returnCode = p.waitFor();
- switch (returnCode) {
- case 0:
- isSuccess = true;
- break;
- case 1:
- break;
- default:
- break;
- }
- } catch (InterruptedException e) {
- e.printStackTrace();
- }
- return isSuccess;
- }
- }
如果要使用,还需以下步骤:
1、在AndroidManifest.xml文件里添加如下权限:
<uses-permission android:name="android.permission.INSTALL_PACKAGES" />
2、进行系统签名。命令如下:
java -jar signapk.jar platform.x509.pem platform.pk8 XXX.apk Signed_XXX.apk
备注:一般可在源码的目录\out\host\linux-x86\framework\下找到signapk.jar,在\build\target\product\security下找到签名文件platform.x509.pem和platform.pk8。
好了,现在大功告成!!!
